怎么把系统变量WriteStat变为0?
<P>今天看CAD帮助文件时无意看到WriteStat变量,觉得很有用。</P><P><FONT color=#3370cc>WRITESTAT System Variable <BR>Type: Read-only<BR>Not saved<BR>Initial value: 1<BR>Indicates whether a drawing file is read-only or can be written to. For developers who need to determine write status through AutoLISP.</FONT></P>
<P><FONT color=#3370cc>0 Can't write to the drawing<BR>1 Can write to the drawing</FONT></P>
<P>但它是个只读变量,不能保存。能用什么方法可以把它变为0呢?</P> 这个变量有什么用? <P>我翻译一下英文你就知道它的用途了。</P>

<P class=body>指示图形文件是只读的还是可写的。 开发人员需要通过 AutoLISP 确定文件的读写状态。</P>
